Phylogenetic placement of Marasmiellus juniperinus

Recent collections and the type specimen of Marasmiellus juniperinus , the type species of the genus, were examined. Phylogenetic placement, based on ribosomal large subunit (LSU) and internally transcribed spacer (ITS) sequences, is within the lentinuloid clade, nested among Gymnopus taxa. This placement dictates genus name usage and phylogenetic position of other putative species of Marasmiellus . The mating system is tetrapolar.
